Abstract: As automotive vehicle frame can be strengthened by reinforcing the tubular frame elements that form the side door openings. A three dimensional core element and rigid foam can be incorporated into each tubular frame element to achieve a significant increase in the frame bending strength, without adding appreciable weight to the vehicle frame.

Abstract: A front crossmember assembly for a motor vehicle. The crossmember assembly serves to support the vehicle radiator, and provides attachments for the front of the vehicle engine, the front recovery bracket, the front fascia and splash shield, along with providing torsional stability to the vehicle front end. The spot welded assembly itself is bolted into the vehicle body, along with the radiator and associated cooling module, built-up, charged and sealed before insertion into the vehicle body, thereby facilitating plant assembly and, where necessary, plant repair, reducing part complexity, vehicle weight, and potential service problems.
